Definitions

  • the invention relates to a volumizer attachment for use with a device that creates an air stream, such as an air curler.
  • the volumizer unit has a concave surface with a plurality of long hair styling fingers protruding in parallel to one another.
  • the volumizer unit is connected to the device with a curved coupling section.
  • the hair styling fingers of the volumizer unit extend approximately perpendicular to the longitudinal axis of the device creating the hot air stream.
  • Volumizers introduce volume into hair that is styled by using an air stream, preferably a hot air stream.
  • Such volumizer devices are typically attachments, which can be attached to a device that generates an air stream, e.g., an air curler or a hair dryer.
  • a volumizer attachment has a coupling piece for mechanical connection to the hand-held device supplying the air stream.
  • the volumizer unit has a plurality of hair styling fingers protruding in parallel to one another away from a concave surface, which is a complementary curvature to the curvature of the human head.
  • the volumizer unit is attached to the device with coupling piece, which is typically designed as a coupling ring. In use, the air stream travels from the device through the coupling section into the volumizer unit. Openings in the base surface and/or in the hair styling fingers of the volumizer unit act as outlets for the air stream.
  • GB2,374,801A discloses a hair styling device of this variety.
  • a traditional hair dryer supplies the air stream to a volumizer attachment.
  • the hair styling fingers of the volumizer unit extend parallel to the longitudinal axis of the hair styling device.
  • An electric motor drive unit is rotatably mounted within the housing of the hair dryer outside of the air flow channel.
  • the electric motor drive unit connects to a coupling piece on the volumizer attachment.
  • the electric motor drive unit thus moves the volumizer attachment in an oscillating rotational motion about its longitudinal axis. Therefore, the hair styling fingers move back and forth in an oscillating motion about the longitudinal axis of the volumizer attachment.
  • An aspect of the present disclosure is to improve upon a volumizer attachment designed to attach to the hair styling device at an angle, so that the volumizer unit, either in whole or in part, may be driven with an oscillating rotational movement.
  • a generic volumizer attachment is rotatably mounted to a hair styling device using a coupler.
  • the volumizer attachment has a rotatably mounted drive shaft inside its coupling section.
  • This first drive shaft includes a coupling piece to connect it to a rotatably mounted second drive shaft in the hair styling device.
  • the output end of the first drive shaft has a drive element arranged eccentrically to the axis of rotation of the first drive shaft.
  • This drive shaft acts as a force converter which converts the rotational drive movement of the drive element into an oscillating rotational movement of the volumizer unit, in whole or in part.
  • the axis of rotation of the volumizer unit is at an angle to the axis of rotation of the drive shaft, whether rotating in whole or in part.
  • the axis of rotation of the volumizer unit is at an approximate right angle to the axis of rotation of the drive shaft.
  • the coupling ring and angle piece form the stator of the rotatably mounted volumizer unit, or the rotatably mounted partial area thereof. Since the volumizer attachment is designed to attach to the hair styling device at an angle, it is necessary to convert the rotational motion introduced via the drive shaft into a drive motion at an angle thereto. This required conversion of force is utilized to convert a rotational movement of the drive shaft into an oscillating rotational movement of the volumizer unit and/or the rotatably mounted part thereof simultaneously with the conversion of force.
  • a drive element is arranged eccentrically with respect to the axis of rotation of the drive shaft. The drive element engages with a force converter.
  • the force conversion may be accomplished by placing the drive element at an end section of the drive shaft which is bent toward the outside in the radial direction and engages in a longitudinal groove about an axis of rotation running at an angle to the axis of rotation of the drive shaft.
  • the measure of the oscillating rotational movement in this embodiment is defined by the measure of the bending and thus the offset of the drive element from the axis of rotation of the drive shaft.
  • the force converter comprises a conversion element in a cardan mount, which reduces friction and the associated wear of the parts from moving against one another.
  • FIG. 1 is a schematic diagram of a volumizer attachment for connection to a device generating an air stream.
  • FIG. 2 is an enlarged schematic diagram of the force converter of the volumizer attachment from FIG. 1 .
  • FIG. 3 is a 90° rotated view of the units from FIG. 2 .
  • a volumizer attachment 1 is designed to be attached at an angle and has a coupling ring 2 , which is not shown in detail, for connecting the volumizer attachment 1 to a hand-held device 3 .
  • hand-held device 3 is an air curler.
  • the hand-held device 3 has a fan (not shown) for generating an air stream.
  • Heating registers 4 located in the housing of the hand-held device 3 heat the air stream generated by the fan.
  • the direction of the air flow is indicated by arrow A.
  • Hand-held device 3 contains a drive unit 5 with a first drive shaft 6 .
  • the drive unit 5 is an electric motor in the depicted embodiment.
  • the first drive shaft 6 extends into the mouth 7 of the air outlet opening of the hand-held device 3 .
  • the first drive shaft 6 has a coupling piece 8 on the end opposite the drive unit 5 .
  • Volumizer unit 9 is separated from the coupling ring 2 by a curved piece.
  • Volumizer unit 9 includes hair styling fingers 10 . Hair styling fingers 10 are subdivided into an area 11 , which is mounted to allow it to rotate in an oscillating manner, and a ring section 12 concentrically enclosing the rotatable area 11 .
  • the rotatable mounting of the area 11 of the volumizer unit 9 is not shown in greater detail.
  • the volumizer attachment 1 has a second drive shaft 13 for moving area 11 of the volumizer unit 9 .
  • Second drive shaft 13 has a coupling piece 14 complementary to the coupling piece 8 of the first drive shaft 6 of the hand-held device 3 .
  • the two coupling pieces 8 , 14 are in torque engagement when the volumizer attachment 1 is connected to the hand-held device 3 .
  • Arrow B shown above the volumizer attachment 1 in FIG. 1 represents the motion of the volumizer attachment 1 when connecting it to the hand-held device 3 .
  • the second drive shaft 13 of the volumizer attachment 1 rotates during operation of the electric drive motor 5 of the device 3 as shown by arrow C.
  • the second drive shaft 13 has a drive element located on the end opposite the coupling piece 14 .
  • the drive element is arranged eccentrically with respect to the axis of rotation of second drive shaft 13 .
  • the drive element is a drive pin 15 in the depicted embodiment.
  • the drive pin 15 engages with a conversion element 16 .
  • Conversion element 16 converts the rotational movement of second drive shaft 13 to a rotational motion executed at an angle to the axis of rotation of the second drive shaft 13 .
  • Conversion element 16 also converts the rotational movement of second drive shaft 13 to an oscillating rotational motion of output shaft 17 .
  • Output shaft 17 is connected to area 11 of volumizer unit 9 .
  • the oscillating rotational motion of output shaft 17 causes area 11 to oscillate and rotate as show by arrow D.
  • the air stream flows from the hand-held device 3 through the coupling ring 2 of the volumizer attachment 1 into the volumizer unit 9 .
  • the bottom of the volumizer unit 9 and individual hair styling fingers 10 have openings for discharging the air stream.
  • the base of area 11 also has openings for allowing a partial stream of air to enter and for supplying the same to the hair held by the hair styling fingers 10 in the area 11 .
  • the design and bearing of the conversion element 16 are described below with reference to FIGS. 2 and 3 .
  • the conversion element 16 is mounted in a holder 18 .
  • Conversion element 16 has axle stubs 19 , 19 . 1 , which engage in corresponding bearing openings in holder 18 .
  • conversion element 16 is spherical and holder 19 is U-shaped.
  • the drive pin 15 is positioned at an angle above the axis of rotation of the second drive shaft 13 and engages in a suitably positioned borehole 20 in the conversion element 16 , as can be seen in FIG. 2 .
  • the holder 18 is connected in a torque-locked manner to the output shaft 17 and is thus rotatably mounted within the volumizer attachment 1 by means of the bearing of the output shaft 17 as shown by arrow F.
  • the rotational movement of the second drive shaft 13 is broken down into two oscillating rotational movements due to the cardan mount of the conversion element 16 .
  • the oscillating rotational movements occur around two cardan axes, namely the axes of rotation D H and D V shown in FIG. 3 .
  • First axis of rotation D H is the axis of rotation of the conversion element 16 about the axis of the two axle stubs 19 , 19 . 1 .
  • Second axis of rotation D V is the axis of rotation of the output shaft 17 . Consequently, the conversion element 16 has a cardan mount.
  • drive pin 15 engages borehole 20 of conversion element 16 , causing conversion element 16 to rotate (see FIG. 3 ). Due to the cardan suspension of the conversion element 16 described previously, this motion is broken down into an oscillating rotational motion of the conversion element 16 about the first axis of rotation D H (arrow G) and a rotational movement of the holder 18 about second axis of rotation D V (arrow F). Rotation of holder 18 about second axis of rotation D V causes output shaft 17 to rotate about the same axis. Output shaft 17 is connected to area 11 of the volumizer unit 9 . Consequently, area 11 of volumizer unit 9 is moved back and forth in an oscillating motion about the axis of output shaft 17 , e.g., by approximately 45°.
  • the conversion element 16 and the holder 18 supporting the conversion element 16 are situated within the volumizer attachment 1 at a distance from the side walls. Thus there remains an adequate cross-sectional area of airflow to be supplied to the volumizer unit 9 .
  • the output shaft 17 is mounted in a bearing point 21 of holder 18 .
  • Bearing point 21 is connected to the wall of volumizer attachment 1 with spokes 22 .
  • the spoke interspace is also designed to supply a sufficient cross-sectional area of airflow.
